Question: 17

Which encapsulation supports an interface that is configured for an EVN trunk?

A. 802.1Q
B. ISL
C. PPP
D. Frame Relay
E. MPLS
F. HDLC

Answer: A

Explanation/Reference:

Restrictions for EVN
• An EVN trunk is allowed on any interface that supports 802.1q encapsulation, such as Fast Ethernet, Gigabit Ethernet, and port channels.
• A single IP infrastructure can be virtualized to provide up to 32 virtual networks end-to-end.
• If an EVN trunk is configured on an interface, you cannot configure VRF-Lite on the same interface.
• OSPFv3 is not supported; OSPFv2 is supported.

Question: 14

What is the purpose of the autonomous-system {autonomous-system-number} command?

A. It sets the EIGRP autonomous system number in a VRF.
B. It sets the BGP autonomous system number in a VRF.
C. It sets the global EIGRP autonomous system number.
D. It sets the global BGP autonomous system number.

Answer: A

Explanation/Reference:

To configure the autonomous-system number for an Enhanced Interior Gateway Routing Protocol (EIGRP) routing process to run within a VPN routing and forwarding (VRF) instance, use the autonomous-system command in address-family configuration mode. To remove the autonomous-system for an EIGRP routing process from within a VPN VRF instance, use the no form of this command.

  • Autonomous-system autonomous-system-number
  • no autonomous-system autonomous-system-number

Question: 22

Which statement describes what this command accomplishes when inside and outside interfaces are correctly identified for NAT?
ip nat inside source static tcp 192.168.1.50 80 209.165.201.1 8080 extendable

A. It allows host 192.168.1.50 to access external websites using TCP port 8080
B. It allows external clients coming from public IP 209.165.201.1 to connect to a web server at 192.168.1.50.
C. It allows external clients to connect to a web server hosted on 192.168.1.50
D. It represents an incorrect NAT configuration because it uses standard TCP ports

Answer: C
